When temperatures get too hot to handle, most of us crank up the air conditioning to keep cool. It does the job, but it's expensive and uses a significant amount of energy. But now an innovation by scientists, primarily from ...
Energy & Green Tech
With the right technology, solar energy has the potential to meet all of the world's electricity needs, but we are still a long way off from that point. Still, governments around the world are setting high objectives for ...
Engineering
Over the past decades, energy engineers have been developing a wide range of new technologies that could power electronic devices, robots and electric vehicles more efficiently and reliably. These include solid oxide cells ...
Energy & Green Tech
Lithium metal (Li-metal) batteries are among the most promising alternatives to widely employed rechargeable lithium-ion (Li-ion) batteries, as they could store more energy and thus extend the battery life of many electronic ...
Energy & Green Tech
To support the ongoing transition to electric vehicles and reduce greenhouse emissions, engineers have been trying to develop batteries that can store more energy, while also operating safely and lasting for long periods ...
Energy & Green Tech
Fuel cells are energy solutions that can convert the chemical energy in fuels into electricity via specific chemical reactions, instead of relying on combustion. Promising types of fuel cells are direct methanol fuel cells ...
Energy & Green Tech
Hydrogen (H2) is an Earth-abundant molecule that is widely used in industrial settings and could soon contribute to the clean generation and storage of electricity. Most notably, it can be used to generate electricity in ...
Engineering
Sunlight shining on specialized floaties can now produce fuel for plants by recovering ammonia from wastewater. Researchers designed a floatable amino-grafted (-NH2) MXene (Ti3C2)-based (AMS) sponge that, when scaled efficiently, ...
Energy & Green Tech
Commercial silicon-based solar cells have made significant improvements in efficiency over the past decade, increasing from around 15% efficiency in 2015 to just shy of 25% in 2025.
Engineering
Researchers have designed a working prototype of a lithium metal battery equipped with a built-in fire extinguisher, which is activated if the battery overheats.
